It is recommended that you buy a voltage stabilizer with at least three times the actual power, because the voltage stabilizer needs to overcome the surge shock of the mains and the starting shock of inductive loads (such as refrigerators, air conditioners, motors, etc.) in actual work.

1.When the voltage stabilizer is used in an inductive load, due to the large instantaneous starting current of the inductive load, it is generally about 3-5 times of the rated current and often exceeds 9 times of the running current (such as refrigerators, air conditioners, washing machines, fans, etc.). Large air conditioners, printing presses, air compressors, water pumps, etc. are all inductive loads), so any voltage stabilizer equipped with inductive loads such as motors and compressors must consider its power reserve. Sufficient margin should be reserved to avoid immediate damage to the voltage stabilizer caused by the inrush current generated when the load is turned on. If the whole plant uses a voltage stabilizer, when starting the machine, avoid high-power inductive loads from starting at the same time, so when purchasing a voltage stabilizer, there should be 1.5 times the reserved capacity. 3 times.

2.Pay attention to the voltage value of the mains power supply, whether it exceeds the input voltage range specified by the selected voltage stabilizer, and whether the three-phase power voltage differs by more than 10v.

3.Before purchasing the machine, it is necessary to consider the future business expansion, whether it is necessary to add equipment, and whether the voltage stabilizer needs to reserve expansion capacity.

4.Whether it is a stand-alone package or a complete plant, a certain reserved capacity should be reserved for the purchased voltage stabilizer to avoid a 100% load rate of the voltage stabilizer. The load rate of the voltage stabilizer is generally 90%, which is more appropriate. . The shape and structure of automatic voltage regulators include desktop, wall-mounted, table-wall dual-use and floor-standing. Different styles should be selected according to the installation location, main purpose, and installation capacity.

5.Industry insiders suggest that when choosing a voltage stabilizer, you should also pay attention to choosing products with high brand awareness, because these manufacturers have reliable quality and considerate service; at the same time, whether the manufacturers have good after-sales service, such as product quality implementation of three guarantees, etc., It is also an important factor that consumers should pay attention to.

Regulator usage specification

1. Access to the mains (according to the national standard for left-zero and right-fire wiring)
①The diameter of the input wire of the access device must ensure ≥25mm2 copper core wire
②The input and output wires of the access device must be tightened
③ Input and output lines must not be reversed
④The front end of the equipment cannot be replaced

2. Access load
The load power cannot exceed the maximum power of the regulated power supply: Example: 50kva. The general load rate is 50kva×0.8=40kw
①All line interfaces of the output line must be connected tightly, otherwise the line will heat up due to the large current, which will affect the effective power.

3. Turn on the regulated power supply (it is strictly forbidden to turn on the load first, then turn on the regulated power supply)
① Please ensure that the computer monitor is turned off and the regulated power supply is turned on.
② Before turning on, measure the input voltage value should be between 304v-456v.
③ Check that the output voltmeter that comes with the machine should be 380v.

4. Do not use excessive load;

5. Please use enough wires;

6. Please be careful to connect the input voltage and the output of the equipment;

7. The output voltage of the equipment and the voltage stabilizer should be unified;

8. Please select the input voltage switch is the same as the power supply voltage;

9. If the fuse is burned out, please check the load equipment;

10. Use the same rated fuse, and cannot use non-rated fuses or wires;

11. Install in a dry and ventilated place.

Regulator Maintenance

A voltage stabilizer is a device that provides a stable output voltage according to the requirements of electrical equipment. There are mainly intelligent numerical control type, auto-coupling adjustment type, high-power compensation type, switch type and so on.

The daily maintenance of the voltage stabilizer should pay attention to 4 points:

1. The voltage stabilizer should be placed in a ventilated, dry, no direct sunlight, no corrosive gas indoor use;

2. The power selected by the voltage stabilizer should be greater than the total power of the electrical equipment;

3. The voltage stabilizer switch should not be used as the main switch of the equipment. The voltage stabilizer switch should be turned on first. After the power output is available, connect different electrical equipment in order from small to large power, and turn off from large to small. Shut down, and finally turn off the switch of the voltage regulator;

4. The switch of the voltage stabilizer should not be turned on frequently, and the time interval for each turn on should be greater than 10 seconds, otherwise the voltage stabilizer may be misprotected or even damaged.
